Illegal immigrants brought to the country as children are fighting for their right to drive in Arizona, claiming in court the state is unconstitutionally refusing to issue them driver's licenses.

President Obama recently issued an executive order that allows certain people who immigrated illegally as children to remain legally in the U.S. and work here.

But Arizona's Gov. Jan Brewerissued her own executive order this summer saying Obama's so-called deferred action program "does not and cannot confer lawful or authorized status or presence upon the unlawful alien applicants."

That order prompted state agencies to prevent those eligible for deferred action from getting a license, Courthouse News Service reported last week.

Brewer's executive order has made it impossible for immigrants who came here illegally as children to "accomplish essential aspects of daily life, such as going to the grocery store, attending church, bringing their children or younger siblings to medical appointments or to school, attending school, and maintaining or obtaining productive employment."

The lawsuit comes as leaders of the United We Dream network voted to increase pressure on President Barack Obama and Congress to pass a comprehensive immigration overhaul to grant more rights to illegal immigrants brought here as children, The New York Times reported Sunday.

Most of the young people who attended this weekend's conference in Kansas City, Mo., don't have legal papers but believe the large turnout by Latino voters on election day proves change is imminent.
